Brief Summary:
The goal of the study is to compare and evaluate safety and efficacy of tesevatinib 50mg versus placebo in patients with ADPKD.

Condition or disease Intervention/treatment Phase
Autosomal Dominant Polycystic Kidney ADPKD Drug: Tesevatinib Drug: Placebo Phase 2

Detailed Description:

Safety and efficacy of 50mg tesevatinib in comparison to placebo in patients with autosomal dominant polycystic kidney disease (ADPKD) will be assessed.

The primary purpose of this study is focused on evaluating the change from baseline in height-adjusted total kidney volume (htTKV) as measured by magnetic resonance imaging (MRI) at Months 12, 18, and 24 in patients with ADPKD treated with tesevatinib or placebo.

If eligible for the study participation, subjects will be randomly assigned to either investigational treatment group or placebo group. Treatment group will receive 50mg tesevatinib once daily for 24 months and control group will receive the placebo once daily for 24 months.

Arm Intervention/treatment
Experimental: Treatment Group
50mg tesevatinib administered once daily for up to 24 months.
Drug: Tesevatinib
A once daily dose of tesevatinib 50 mg in a round tablet form of white to off-white color.
Other Name: KD019

Placebo Comparator: Control Group
Matching placebo administered once daily for up to 24 months.

Primary Outcome Measures :
  1. Change of height-adjusted total kidney volume (htTKV) in participants with ADPKD treated with tesevatinib 50mg or placebo. [ Time Frame: 12 months ]
    Change from baseline of the htTKV will be measured by magnetic resonance imaging (MRI) at Months: 12.

  2. Change of height-adjusted total kidney volume (htTKV) in participants with ADPKD treated with tesevatinib 50mg or placebo. [ Time Frame: 18 month ]
    Change from baseline of the htTKV will be measured by magnetic resonance imaging (MRI) at Months: 18.

  3. Change of height-adjusted total kidney volume (htTKV) in participants with ADPKD treated with tesevatinib 50mg or placebo. [ Time Frame: 24 month ]
    Change from baseline of the htTKV will be measured by magnetic resonance imaging (MRI) at Months: 24.


Secondary Outcome Measures :
  1. Safety and Tolerability of tesevatinib 50mg administered once daily in patients with ADPKD measured as incidence of treatment-emergent adverse events. [ Time Frame: 24 months ]
    Incidence of adverse events occurring at the duration of the study will be identified with the following assessments: 12-lead ECGs, ocular evaluations, clinical laboratory tests, echocardiograms, and physical exams.
